I seem to be getting this error on several mailboxes within the environment. <br />
<br />
When issuing Remove-Mailbox -Identity &quot;mailbox&quot; -User &quot;user&quot; -AccessRights FullAccess -InheritanceType All <br />
<br />
I get the following error <br />
<br />
WARNING: Can't remove the access control entry on the object &quot;CN=xx,OU=xxx,OU=xxx,DC=xx<wbr />x,DC=xxx&quot; for account &quot;DOMAIN\user&quot; because the ACE doesn't exist on the<br />
object.<br />
<br />
Does anyone know how to fix this or get around it? Thanks in advance
